+# Script to swap core networking modules in a GMS userdebug device to AOSP modules, by remounting
+# the system partition and replacing module prebuilts. This is only to be used for local testing,
+# and should only be used on userdebug devices that support "adb root" and remounting the system
+# partition using overlayfs.
+#
+# Usage: aospify_device.sh [device_serial]
+# Reset by wiping data (adb reboot bootloader && fastboot erase userdata && fastboot reboot).
+#
+# This applies to NetworkStack, CaptivePortalLogin, dnsresolver, tethering, cellbroadcast modules,
+# which generally need to be preloaded together (core networking modules + cellbroadcast which
+# shares its certificates with NetworkStack and CaptivePortalLogin)
+#
+# This allows device manufacturers to test their changes in AOSP modules, running them on their
+# own device builds, before contributing contributing the patches to AOSP. After running this script
+# once AOSP modules can be quickly built and updated on the prepared device with:
+#   m NetworkStack
+#   adb install --staged $ANDROID_PRODUCT_OUT/system/priv-app/NetworkStack/NetworkStack.apk \
+#   adb reboot
+# or for APEX modules:
+#   m com.android.tethering deapexer
+#   $ANDROID_HOST_OUT/bin/deapexer decompress --input $ANDROID_PRODUCT_OUT/system/apex/com.android.tethering.capex --output /tmp/decompressed.apex
+#   adb install /tmp/decompressed.apex && adb reboot
+#
+# This has been tested on Android T and Android U Pixel devices. On recent (U+) devices, it requires
+# setting a released target SDK (for example target_sdk_version: "34") in
+# packages/modules/Connectivity/service/ServiceConnectivityResources/Android.bp before building.
